' the bearings of a motor can be burned-in Heretofore it llflS'b G'EIlthe general practice to scrape the bearings and it has been 1mpossibleto obtain an even or uniformly Furthermore the gold methodfof scrapingbearings has been long;

smooth a surface.

and tedious asi'well asexpensive. I 7 .It is an object of the presentinvention to provide a means for burning-in the bearings, this meansbeing adapted to becoupled to the drive axle of a motor vehicle so thatan efiicient bearing surface can be quiclrly obtained instead of theexpensive and ineflicient surface that hasbeen obtained here tofore bythe hand process.

With the foregoing andother ob ects 1n view which will appear as thedescription proceeds the. invention resides in the combi-.

nation and arrangement of parts and in, the

details of construction hereinafter described and claimed, it beingunderstood that, within the scope of what is claimed, changes in theprecise embodiment of the invention shown can be made without departingfrom the spirit of the invention.

In the accompanying drawings the pie ferred form of the invention hasbeen shown.

In said drawings Figurel is an elevation showing the at tachment appliedto the drive axle of a' tractor, an engine block being shown in positionfor-the burning-in of the bearings.

Anannular flange 11 is formed on the sleeve and is adapted to be bolted or otherwisesecured to'a collar 15 onthe end of the'engineshaft 16.

The block of the engine has been indicated at B and is secured on theslide 3 in any preferred ma'nneiy'as by'means ofbolts 17 extendingthrough'the slide and having their heads seated in counter sinks 18.Detachably-secured to one end of the engine block B is'atapered-extension 19 provided at its small end witha bearing 20 in whichthe shaft?) is adapted to rotate. This extension 1s provided with acover 21 which also ex- .tcnds over the inverted block B1 so as tocompletelyhousc the shaft 16. The cover maybe provided with a handle 22to facilitate the removal thereof and lubricating means'such' a's-afunnel 23 having a delivery tube 2% canbe mounted in the cover forlubricating the" engine during the burningbe provided. with an oilcup-2:3, as shown particularly in Figure 7." 1 V ltwill be" apparentfrom the foregoing that the rear axle of a motor vehicle canbe coupledreadily to the shaftof anengine,
